Abstract

A wall section as a constituent of a container, bottle, unit or component can be turned inside out from a concave final position into a convex one and vice versa. The wall section and the adjacent region, for example of a container wall, especially the entire container, are made of an elastically deformable material. The wall section has a stable position in at least one of the final positions, preferably in both. The volume of the container can be reduced by pressing in the wall section which can be turned inside out. A plurality of such containers can be stacked. If the wall section which can be turned inside out is designed as a roof-shaped area, with buckling lines subdividing the roof-shaped area, a tube for insertion and removal of pourable material can be tippably mounted on one of the subdivisions of the roof-shaped area. It can be tipped from a position parallel to the axle for production and filling to an inclined position for delivery of the pourable material, in a spring-loaded fashion. The inside of the end of the tube can be sealed by means of sealing elements in the container or in a screw cap, during retraction. The wall section can be used in a large number of units or components in which tipping movements are necessary.

Description

WALL SECTION AS A COMPONENT OF A CONTAINER, DEVICE OR COMPONENT The invention relates to a wall section of a container, a bottle, of a device or component. The object on which the invention is based is to design the wall section so that it occupies at least two different positions can.

If the wall section is part of a container, it can be Change the volume of the room. In addition, parts of the container can be divided into different bring mutual situations. The wall section should be applied to devices or components Allow tilting or folding movements, e.g. B. with flaps or toggle switches.

This object is achieved according to claim 1.

The evertable wall section can, for. B. by hand from his put one in his other position. If it is part of a container, it leaves the interior of the container is reduced by pressing in the wall section. You can thereby z. B. after partial removal of a perishable filling good Shrink air space and thus reduce the amount of trapped atmospheric oxygen.

In general, one becomes an arrangement with two stable end positions of the reversible wall section, e.g. with toggle switches. But there is Applications in which only a single stable end position, e.g. B. at one Container with the maximum volume required. The consumer can then use the Press in the wall section just as far as necessary to remove the product is.

When using one or more wall sections that can be turned inside out can also be one part or several parts of the container in other positions compared to the remaining part of the container, which makes the consumer happy responds and the sale of such containers is beneficial.

The wall section can be made of elastic plastic but also other things consist of elastic material, e.g. B. made of paraffinic cardboard or metal foils. The wall section can be made of plastic with the adjoining area, but Be part of a cardboard box.

Many other material combinations are possible.

Developments of the invention According to claim 2 it can be achieved that only a certain area z. B. a container wall as an invertible wall section serves and that this wall section is clearly defined. This allows the aesthetic Improve the impression made by the container.

According to claim 3 can be a clear structure of the evertable wall section achieve. It is divided into individual wall elements, which are even or curved which in turn increases the aesthetic appeal.

According to claims 5 and 6, the target buckling lines, Depending on the plastic material used, they can be designed as grooves or film hinges. The channels can have any cross-sectional shape and are related to the inside or outside ( on a container).

According to claim 7, the evertable wall section takes a considerable amount Area part of at least one side wall of a container, it can be Reduce the volume of the room considerably so that it takes up much less space than its maximum capacity is equivalent to. This results in a space saving when storing such containers, at the manufacturer, at from the filling plant, in trade and during transport. There are also savings of packing material when packing several such containers on delivery from Manufacturer to the bottling company.

With the consumer there is a saving in volume as soon as a Part of the content is consumed. But it is more important that it also reduces the volume of waste empty container is reduced.

If plastic containers are blown in connection with an extruder system, normally the smallest clear width of the container must be at least as large its like the diameter of the mandrel of the extruder. According to the training according to claim 7, however, a container can be created, the clear width of which decreases the turning in of one or two opposing wall sections is considerably smaller can be than the diameter of the extruder mandrel.

According to claim 8, the space requirement of the container for logistic Purposes before filling or after at least partially emptying further thereby reduce the fact that several such containers are stackable. In one by everting The resulting indentation of the container can be a bulge of another Insert the container correctly.

According to claim 9, they have two broad sides opposite one another of the container each have an invertible wall section, the effect is to save space especially essential.

According to claim 10, such containers, after their consumption Contents to be used by children for play, especially if it is roughly cuboid Containers or bottles which (preferably after cutting off their closure mouth) can serve as building blocks.

According to claim 11 can be the evertable wall portion, the preferably Part of the container itself is to use a tube that is used for filling of the container as well as for removing the product from a stable position to pivot into another stable position. For many use cases, a is oblique pipe arranged to the container axis is desirable. A typical example is cleaning of lavatory basins where cleaning agents are placed under the inwardly overlapping edge should be sprinkled.

It is cumbersome and expensive to have a container with one at an angle though but immovable pipe to fill. According to claim 11 is therefore the possibility created to fill such containers while the pipe is in the vertical position Container also stands vertically, while the consumer has the option. Has, to tilt the pipe into a stable incline.

While it is possible in principle to use a To use invertible wall section in the manner of a conical surface, can be Claim 12 achieve a precise snap action, namely in that the evertable Wall section is formed in the manner of the surface of a hipped roof, the pipe attaches to one of the main roof surfaces.

According to claim 13 are two principally opposite arrangements possible. The longitudinal direction of the tube is parallel to the container axis, either when the roof surface is everted or when it is everted. In the first case the container can hold a particularly large amount of product, in the second case transport space is saved when shipping filled containers, as the tube partially protrudes into the container. In both In cases, an imaginary base area of the roof surface must be inclined, which means that a level that contains the eaves kink lines of the roof area, under one is inclined at an acute angle to the container axis and that the pipe with the roof surface in the opposite sense includes an equally large acute angle.

According to claim 14, a particularly beautiful arrangement can be created, namely in which the pipe rchtwinkliq on one in the fill state right angled to the container axis arranged surface sits.

This requires a strong incline of the base of the roof surface opposite a plane transverse to the container axis.

According to claim 15, a possibility is created through the pipe Buckling of the roof surface to be sealed on a plug, which is part of the container is and protrudes inside. It is therefore not necessary to container this Type to be provided with a screw or snap lock. Rather, one is enough the outer tube opening closing, sealed film.

A further development according to claim 16 also relates to a pipe (Tube) which is attached to a closure part for the container and allows a perfect sealing of the pipe on its inside. And that is what is inside The end of the tube is pivoted over a pin, one being arranged at the inner end of the tube Plate together with other inner wall parts of the pipe, the pin under seal encompasses.

According to claim 17, a rib can be arranged on the other side of the pin, so that the plate engages in a gap between the pin and rib with sealing, whereby the seal is improved.

Finally, you can according to claim 18 on the plate on the inside Do without the end of the tube, but still remove the pin from the inner wall parts of the Grip around the pipe to seal it.

Embodiments with further features of the invention are in described below with reference to the drawings.

Figures 24 to 26 show in axial section and in perspective view (looked into the interior of the closure part and the roof surface) another Sealing of such a tube.

Figures 1 to 6 show a container in the form of a flat bottle 1, made of elastically deformable material, preferably plastics such as polyolefins is blown. On both of its broad sides it has a wall section that can be turned inside out 3. In their position according to Figure 2, both wall sections 3 have a convex shape, see above that the bottle 1 has the maximum capacity. In their position according to Figure 3 are both wall sections turned inside out, and the bottle has minimal capacity. Only one wall section can also be turned inside, while the other protrudes outwards. Each non-foldable wall section follows a desired folding line 5 into the broad side of bottle 1.

FIGS. 4 to 6 show other forms of the evertable wall sections In FIG. 5, the left half relates to the shape according to FIG. 4, the right half the shape of Figure 6.

The target kink lines result from the molding process, but can also be used advantageously through channels for blown and injection-molded objects be educated.

For containers that are manufactured in an injection molding process can, the desired folding lines can be designed as film hinges.

During the blowing process, the bottles are in their position according to FIG produced with everted wall sections 3. To save space during transport to a bottling company, the Wall sections 3 then be turned into the position according to FIG.

When filling, the wall sections 3 either snap again by themselves outside, or the bottle is briefly placed under internal overpressure around this to reach. After removing part of the product, the consumer can first press one, later also the other wall section 3 inwards and thereby reduce the air space above the product. Bottles can after emptying of the same type can then be used as building blocks. You can use the neck of the bottle for this cut off. Outside on the broad sides and / or narrow sides of the bottle can matching pins 7 and recesses 9 may be formed, of which (in Figures 1 and 3) only some are shown, exaggerated.

Figures 7 to 10 show a bottle in which the desired crease lines 5 are formed by channels 19 of rectangular cross-section.

The entire evertable wall section 3 is divided into wall elements here, namely a rectangular main element 11, the right and left secondary elements 13 are also rectangular in shape, but are adjacent to a smaller width. Above and a secondary element 15, which is also rectangular, is provided at the bottom. In the end triangular secondary elements 17 are present at the corners. The minor elements are separated from each other by desired folding lines 5, which also have an inner shape. figure 8 and 9 show the positions with on or

everted wall elements in side view. Figure 10 shows both Positions, solid or dashed, in an axial section along line X-X in Figure 7.

FIG. 11 shows another cross-sectional shape of the desired folding lines forming channels 19.1. To avoid horizontal pieces of surface, use the dust catcher form, the grooves 19.1 have a triangular shape, with the lower surface from the inside out runs obliquely downwards on the outside.

Bottles that can be easily stacked can also be used if only one of the two opposite broad sides is designed as an invertible wall section, such as Figures 12-15 show. The back 21 of each bottle is rigid, during each a wall section 5 which can be turned inside out is provided on the left which is shown everted in FIG. 12 and inversed in FIG. figure 14 and 15 show how bottles with turned-in wall sections 5, respectively the back of one bottle into a free one resulting from an indentation Inserts space. If a large number of bottles are stacked one inside the other as shown, so it is hardly important that at one end there is still a back to the outside protrudes.

Figures 16 and 17 and the following figures show an application a turn-over wall section (albeit to change the volume), mainly to change the position of a pipe 32 that is used for filling and emptying of the container is used. The evertable wall section here has the shape of a roof area 30, especially that of a hipped roof, where the ridge and eaves each have one Form target kink line, namely a ridge kink line 34 and two eaves kink lines 36 and 37. The two main roof surfaces are located between these folding lines 40 and 41, of which only the side edges can be seen in FIGS. 16 and 17. These Side edges also form intended kink lines between the main roof surfaces and the two secondary roof surfaces 42, of which only the front one can be seen. The perspective The following drawings show the roof areas more clearly.

The pipe 32 only penetrates the right main roof surface 41 (FIG 16 and 17), the pipe axis forming an acute angle with the main roof surface 41 includes ß. The eaves kink lines 36 and 37 lie in a common imaginary Plane 44, which is in the position according to FIG. 16 with the central axis 46 of the bottle as well includes an acute angle ß. The roof major surface 41 and plane 44 are inclined in the opposite direction. This arrangement ensures that the pipe axis in the Central axis 46 of the bottle falls. Below level 44, the bottle has a triangle surfaces 45 that cannot be turned inside out.

If the roof surface is turned inside out, namely in the position according to Figure 17, so the tube 32 is inclined to the central axis of the bottle. Both end positions of the roof surface 30 correspond to stable positions. The position of Figure 16 is suitable for filling the according to Figure 17 for removal, especially when the container contents at should be dispensed sideways with the bottle upside down. To save space can you can also transport containers with a kinked tube 32, at least for filling Operation, in the case of fillings with air space also from there to the consumer.

In the embodiment according to Figures 18 and 19, the imaginary plane is i.e. the base of the roof surface 30 is arranged at a much more steep incline than after Figure 16 and 17. The individual roof surfaces and their folding lines have the same Reference symbols as in FIGS. 16 and 17 and make the relationships clear. Triangular surfaces 45 of the container are again immutable. The upper main roof surface 41 is standing here horizontally, i.e. transversely to the joint axis.

The front main roof surface 40 in FIG. 1B is preferably below inclined to the same angle with respect to a perpendicular, as a corresponding rearward one Container area 47. Despite the steeply inclined roof area, this results in a symmetrical appearance.

When the roof surface buckles, the eaves kink lines 36 remain and 37 in their positions as the ridge kink line 34 travels inward so that then all roof surfaces run inwards against the ridge kink line 34, and that Tube 32 is inclined. In Figure 19 one looks into the indented roof surface.

The arrangement of the desired folding lines can also be reversed in this way be that the tube is inclined with the everted roof surface, but with the everted Roof surface parallel to the container axis. In the latter position, the pipe axis falls no longer coincides with the container axis, but runs parallel to it.

FIGS. 20 and 21 show a similar embodiment in a vertical longitudinal section like Figures 18 and 19. However, here the tube is 32 µm 900 swivel. An inwardly protruding plug 50 is provided in one container wall. Will when inverting the tube 32 with its main roof surface 41 around the eaves kink line 37 pivoted, so its inside reaches the stopper 50, whereby the container contents is sealed to the outside. The location of the other parts, especially the roof surfaces and the desired kink lines result in turn from the reference symbols.

Containers of this type can be filled with a very simple Closure are provided, for. B. only with a sealed film while they are sealed at the consumer by turning them into the position according to FIG. 21 can.

The desired folding lines are in the exemplary embodiments according to FIGS. 16 to 21 preferably designed as channels in the following exemplary embodiments on the other hand as film hinges.

Figures 22 to 26 show a bottle cap pivotable with it attached tube 52, which is generally only intended to be a filling material to be dispensed in the form of a paste or liquid, but not for filling a container is intended. The closure is made in one piece from polyolefin, preferably from polypropylene injection molded.

A closure part 54, which is to be attached to a bottle mouth may have an internal thread, has a cover plate 56 with a recess 58, in the one roof surface 30 of the type described above is housed. Do it again the reference numerals clearly show the positions of the fold lines. Here are also nominal kink lines 60 and 61 can be seen, which the secondary roof surfaces 42 with the main roof surfaces 40 and 41 connect. The tube 52 has a rectangular outer and inner cross-section and penetrates the roof main surface 41 with a seal. On the side of the tube 52 are seated wings 63 to cover the recess 58 in the closed position.

The tube can be moved from the illustrated removal position into a Closed position be moved, the roof surface with its elastic parts for a snap action cares. The tube with its wings is moved over a dead point and is from the roof surface either to the removal position shown or almost to moves the closed position. The user then only needs the entire tube into the opening.

As FIG. 23 shows, there is an annular seal on the cover plate 56 within 65 a pin 67 is provided. It serves to seal the inner (in Figure 23 lower) End of the tube 52 and can, according to the cross section of the tube, round or approximately cuboid. The left wall 70 of the tube 52 in FIG is extended downward beyond the right wall 71. The back and the front Wall of the tube end at the bottom in a sloping rim 73. When closing the The inner end of the tube encompasses the pin 67 under elastic tension and ensures the sealing of the closure part and thus the bottle or container. The lower end of the wall 70 rests against the lower surface of the peg 67. The two Side walls 72 encompass the pin 67 laterally, and the lower edge of the wall 71 presses against the left face of the pin. The side walls are preferably tapered of the cone slightly against the tube.

Figures 24 to 26 show another form of sealing the interior Tube end. Figures 24 and 25 are partial axial cross-sections through a closure part. Figure 26 shows the inner end of the tube and the parts used for sealing. One looks from below against the cover plate 56 and into the upturned one Roof area into it.

The inner end of the tube 52 carries a transverse to the longitudinal axis Plate 80. The tube has a side opening 82, through which the filling material in the tube gets. At some distance behind the pin 67 (on the right in the figures 24 to 26) there is a rib 84, the same height and width as the Cones.

A gap 86 remains between the two.

The dimensions of pin 67, rib 84, inner end of tube 52, Plate 80 and opening 82 are selected to match one another so that the inner end of the tube is reliably sealed in the closed position according to FIG. Here the plate 80 engages in the gap 86, while the two side walls 72 of the Tubes encompass the side walls of the pin 67. The lower end of the Wall 71, namely the part below the eaves kink line 37, lies against the left end of the cover plate 56. All of this takes place under elastic tension, so that a reliable seal is achieved. Instead of being rectangular as shown, pin 67 and opening 82 can also be round.
